A text in English: The disadvantage of zoom lenses is that the focal complexity and number of lens elements required to achieve a range of focal lengths is much greater than for prime lenses.
The same text in Swahili:
Ubaya wa lenzi za kupanua au kupunguza mwonekano ni kwamba utata wa kiangalifu na idadi ya elementi za lenzi zinazohitajika kufikia urefu wa kiangalifu ni kubwa zaidi kuliko za lenzi kuu.
